Two lamps connected in series with an open switch and a cell The circuit diagram shows a circuit with two lamps connected in series. If one lamp breaks, the other lamp will not light. The current is ...

Find the voltage v1 and the currents I1 and I2 for the circuit shown. To solve this problem first find the total current going through the 14 ohm resistor. To do this find the effective resistance of ...

Almost four decades since its existence was first proposed, a fourth basic circuit element joins the canonical three. The 'memristor' might herald a step-change in the march towards ever more powerful ...

Current is a measure of how much electric charge flows through a circuit. The more charge that flows, the bigger the current. Current is measured in amperes. The symbol for ampere is A. For example, ...

Electronic circuits are integral parts of nearly all the technological advances being made in our lives today. Television, radio, phones and computers immediately come to mind, but electronics are ...
